MULTIPLE AMPLIFIER COMBINATIONS

© 2002 Directed Electronics, Inc
The Directed 600d/1100d subwoofer
amplifiers can also be used in multiples
of the master/slave combinations
allowing for unlimited expansion to a
systems subwoofer section. To use
multiples of amplifier combinations the
following directions must be adhered to
for best results.
„ AAuuddiioo ssiiggnnaall - Divide the head unit
or processor audio signal to the
master amplifiers by using RCA Y
adapters. Be sure to divide them an
even number of times to ensure the
input level at each master amplifier
is matched.
„ RReem moottee SSuubb LLeevveell CCoonnttrrooll - The
Remote Sub Level Control cable can
be divided several times to connect
to each master amplifier. This can
be accomplished by using one or
more Directed Remote Sub Level
cable splitters. Standard single-to-
double phone line splitters and
accessories from a local electronics
store can also be used.
For systems with more than two
master/slave combinations, use
multiple single-to-double splitters.
Do not use phone splitters that
divide the signal more than once
per splitter, or splitters designed for
multiple uses.
„ AAm mpplliiffiieerr ccoonnffiigguurraattiioonn - Set up
each master/slave amplifier combi-
nation as described for the combi-
nation type being used. (Refer to
the
Parallel Synced Gain or the
External Synced Bridged section of
this guide for amplifier and speaker
connection descriptions.)
